Video: Microsoft’s Blu-ray attack on Mac

Microsoft has posted a new video that touts Windows 7’s support for Blu-ray Disc and why that makes PCs better than Macs. It’s cute. It’s also a big ad for “Avatar,” by the way.

A few notes: Windows Media Player can play Blu-ray movies only if the computer manufacturer has installed the appropriate firmware. Otherwise, third-party software is required. And, of course, a Blu-ray Disc drive would be needed.

Blu-ray format generally is 1080p HD video. It looks great on a big TV, but you don’t necessarily need that quality on a 17-inch laptop monitor. And you can download or rent 720p HD movies via iTunes, for instance, on both PCs and Macs.
